Max,
Lay the leading (side away from you as you scrape) edge flat on your stone & do a dozen or so back & forth strokes. The knife must lay flat as you are doing this. The knife should now either have a razor sharp edge or the burr will be on the "wrong" side of the knife (the side toward you while scraping) If this is not so, then continue until you get either the razor sharp edge and/or the curl (burr) This action moves the relief, as Tom Blodgett calls it, back towards the heel of the knife. With a very light stroke or two on the back side of the knife (flat again) with the side toward you as you scrape, you should achieve the desired edge. Now go to your crock sticks & with the back side angled away from the stick at about the two o'clock position, a couple of light strokes to set the burr or curl. Thence to a sharpening steel or burnishing rod to maintain. Go back to the crock sticks as needed & steel for refinement/realigning. When the knife fails to hold an edge, then it is time to go back to the stones. With proper sharpening, a knife should last a long time. The tendency is to run to the stones every time the knife needs sharpening. Doing this removes too much steel too fast. With the sticks & steel you can preserve edge & knife almost indefinitely.
Please let me know if you need further info inre sandpaper vs. stones, steels, etc. or anything re above technique which you find to be unclear.
Best,
john
